Orbital unit tracks under ground coverage are indicated in red in the figure below.
Satellite release was 19.4 seconds early (shouldn't have much impact)
Object B which could be the spacecraft has now been catalogued:
39477/2013-073B in 4306 x 64810 km x 26.65°
Objects 2013-073A and 2013-073B have now been switched; A becomes the S/C
AFAIU Briz-M hasn't been catalogued

I rather think the object cataloged in the 4300 x 64800 km orbit
is the Briz-M, and it's the payload that hasn't been found yet.
You'd expect an orbit manuever by the payload by now, no?

The 4 304 x 64 839 km x 26.64° orbit is dated December 11 and is close to the published by Khrunichev achieved S/C injection orbit which was 4251 x 64889 km x 26.76°. Remember that Briz-M performed 2 more firings (one of 15 seconds, the other of 100 seconds) after S/C separation and should be in a very different orbit...
Object A, the spacecraft, was in the following orbit at epoch Dec 15, 1141UTC:
30722 x 65023 km x 2.06°
Briz-M doesn't seem to have been catalogued

Is it a successful delivery/mission?
The first telemetry signal was acquired by our Paumalu ground station in Hawaii at 17:48 UTC, putting the satellite under the control of Inmarsat’s mission operations team.

I-5 satellites will deliver high-speed mobile broadband communications for deep sea vessels, in-flight connectivity for airline passengers, streaming high-resolution video, voice and date to the enterprise sector, and secure solutions for government customers.Dear Santa...
In a decade or so, I shall own a few Satellites to empower my nation.
1st Boeing Built Inmarsat-5 Satellite Successfully Completes On-Orbit Testing
Satellite handed over for high-speed broadband service
EL SEGUNDO Calif., March 11, 2014 -- Boeing's [NYSE: BA] first of four satellites for Inmarsat's Global Xpress network, has passed all of its on-orbit testing and has now been handed over to Inmarsat.
"This is an important milestone for Global Xpress," said Rupert Pearce, CEO of Inmarsat. "The testing of the Boeing built platform and payload has been completed and shown to meet all the specifications. This is a testament to the dedication of Inmarsat’s Global Xpress team and the skill and professionalism of our partners: Boeing and iDirect."
The high-speed mobile broadband satellite, launched on Dec. 8, will support a wide range of government and commercial customer uses, including in-flight connectivity, communications for vessels at sea, streaming video and other voice and data services.
"This delivery is the first of the significant milestones we expect to accomplish during this landmark year in the Boeing-Inmarsat relationship," said Craig Cooning, chief executive officer of Boeing Satellite Systems International.
Boeing is under contract to build four Inmarsat-5 satellites, with two more scheduled for completion and launch by the close of 2014. The fourth satellite is scheduled to be delivered in 2016. The Inmarsat-5 satellites carry a secondary payload that Boeing Commercial Satellite Services will lease to potential government customers through a reseller agreement with Inmarsat.
