What are the chances of someone flying up a cubesat or something else to get a visual of what gone wrong with the deployment of SXM-7?

GSSAP probably already has as that is one of their government mission services.

GSSAP:
...
Geosynchronous Space Situational Awareness Program (GSSAP) satellites are a space-based capability operating in the near-geosynchronous orbit regime supporting U.S. Space Command space surveillance operations as a dedicated Space Surveillance Network (SSN) sensor.

GSSAP satellites collect space situational awareness data allowing for more accurate tracking and characterization of man-made orbiting objects. From a near-geosynchronous orbit, it has a clear, unobstructed and distinct vantage point for viewing Resident Space Objects (RSOs) without the interruption of weather or the atmospheric distortion that can limit ground-based systems. GSSAP satellites operate near the geosynchronous belt and have the capability to perform Rendezvous and Proximity Operations (RPO). RPO allows for the space vehicle to maneuver near a resident space object of interest, enabling characterization for anomaly resolution and enhanced surveillance, while maintaining flight safety.
...
GSSAP declared Initial Operational Capability (IOC) on Sept. 29, 2015.

According to Space Intel Report, SiriusXM reported that its SXM-7 satellite has already been totally lost.

It sorta reads like the satellite partially or even mostly works, but it isn't performing to contractual requirements, so it's useless to SXM and thus a total loss for insurance purposes. SXM's payload is probably somewhat unique, so I'll be curious to see if the insurance company ends up just de-orbit/graveyarding it.
Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT), PAZ+Starlink (Falcon 9 FT), Arabsat-6A (Falcon Heavy)
Pilgrimaged to: Boca Chica (09/19 & 01/22)

XM Radio LLC (“XM Radio”), a satellite digital audio radio service (“SDARS”) licensee, hereby applies to extend its license for the XM-3 spacecraft, call sign S2617, for an additional five-year term through April 20, 2026.
...
XM-3 is assigned to the 85.15° W.L. orbital location, where it is being flown with an east-west stationkeeping tolerance of +/- 0.1 degrees in formation with the XM-5 in-orbit spare spacecraft.
...
XM-3 serves as one of XM Radio’s two primary operational spacecraft for delivering SDARS programming.5  The spacecraft remains capable of fulfilling that function throughout the term sought in this extension request.  Specifically, XM Radio calculates that ample fuel is onboard the XM-3 spacecraft for the spacecraft to continue providing reliable service through April 2026.
...
As discussed in the attached technical certification, the XM-3 satellite’s overall health is good, and there are no material issues with the spacecraft.
...
 XM Radio has confirmed that at the conclusion of the requested renewal period, the spacecraft will have sufficient fuel to be placed into disposal orbit at the altitude previously submitted, which complies with the IADC standard.
...
Technical Certification
In support of the foregoing request for extension of the XM-3 license for an additional five-year term, I hereby certify that:
1.The estimated total remaining space station lifetime for XM-3 is March 2029.
2.XM-3 has no single points of failure or other malfunctions, defects, or anomalies during the space station operation that should affect its ability to conduct end-of-life procedures as planned.
3.Remaining fuel reserves on XM-3 are adequate to complete de-orbit as planned.
4.The XM-3 telemetry, tracking, and command links are fully functional.

Sirius XM Q1 2021 Earnings call
Quote
With respect to the one-time items, our results reflect a $220 million noncash impairment charge for the SXM-7 satellite failure, which was announced in January. We have issued a request for proposal to construct a new satellite to replace SXM-7, and we're currently working through the insurance process and will book the likely insurance recovery in a future period.

RFP for SXM-9 satellite has been issued.

SXM-7, launched by SpaceX in December 2020, was due to be the first satellite in SiriusXM’s third-generation constellation.

However, SiriusXM has been unable to use the spacecraft for satellite radio service after it suffered a payload failure shortly after launch.

Neville said SXM-7 has a secondary payload that is functioning for a separate service she declined to detail.

When asked what kind of service SXM-7 is providing, she said, “it’s not something we’ve previously disclosed.”
