It's probably image distortion, or the angle, or something like that

Is this a new RLV-TD or the same one that was flown last year? The wings look burned but that might just be the lighting.

Is the RLV so fat or the image is stretched out?

The image is distorted.

A new one - the first one was not planned to be recovered.

Yeah, it's a new one. As you say, the first one wasn't planned to be recovered, although aircraft sent to the ocean touchdown site said they did see that the RLV-TD had touched down on the ocean surface intact, after which it sank beneath the waves. I wonder if that original model could somehow be salvaged? It could make for a decent museum piece.

ISRO Chairman lauds latest SpaceX milestone as a 'quantum leap', says ISRO is working in parallel towards RLV and reusable rocket stages
Quote
 "Our research and development department is working on three technology demonstrators. First one on the orbital re-entry of the vehicle, second on the landing of the reusable launch vehicle on the airstrip and third on reusable rocket stages. Isro's research work on these three technologies is simultaneously going on and we hope to do a second technology demonstrator test (first experiment on reusable launch vehicle was in 2016) within two years."

ISRO to test reusable launch vehicle soon

Quote
The Indian Space Research Organisation (ISRO) will soon carry out another major test for its reusable launch vehicle (RLV) in which the vehicle will be flown to a height of 3 km by a helicopter and let free to land autonomously at an airstrip in Challakere in Chitradurga district.

Quote
This would be the second test for the vehicle after the first one in 2016 demonstrated that the RLV could land autonomously in the sea after being taken to an altitude of 65 km. Talking about the upcoming test, S Somanath, Director of the Vikram Sarabhai Space Centre, said the test will be carried out at the airstrip, owned by the Defence Research and Development Organization within 6 months. "After this test, we will integrate the vehicle into a new rocket which will take it up into orbit for it to return," he said.

This will be the Landing Experiment (LEX)

I wonder what height the Dreamchaser was dropped from, just for comparison?

EDIT: Wikipedia says Dreamchaser was dropped from 4.3 km altitude

In a bid to fulfil its dream of the manned mission, Indian Space Research Organisation (Isro) is gearing up for the second demonstration test of the reusable launch vehicle (RLV) next year. However, this time, the RLV will be tested on an airstrip and not on the sea.

Isro chairman K Sivan said, "We will conduct an RLV test sometime next year where a helicopter will take the vehicle to a height of 3 km and from that height, it will be dropped. The RLV will then glide and land on an airstrip."

Quote
Isro conducted the first demonstration test of India's winged body aerospace vehicle on May 23, 2016. A solid rocket booster carrying RLV-TD lifted off from Sriharikota and coasted to a height of 56km. At that height, RLV-TD separated from HS9 booster and further ascended to a height of 65km and then started its descent and successfully glided down to the defining landing spot over the Bay of Bengal.

Sivan said, "The third experiment will include testing the RLV from the orbit. The vehicle will be integrated into a new rocket, which will take it up to the orbit. There, the vehicle will get detached and re-entre the earth's atmosphere and land."

I think the Indian media are once again mangling perceptions, by mentally associating the RLV-TD and its objectives with those of the very famous US Space Shuttle program. ISRO has never indicated that reusable launch technology development was particularly aimed at manned spaceflight. Perhaps it one day could be, if future use of this technology proves successful - but all previous roadmaps seemed to show RLV being developed primarily for low-cost satellite delivery to orbit.
