The same image of T-50-2LL in higher resolution.
It was indeed taken at Gromov Flight Research Institute earlier today.
Note the stylised "LL" (in Cyrillic) graphic on the vertical stabiliser, acronym that stands for Letayushaya Laboratoriya - flying lab.

1st flying Su-57 prototype T-50-1(501 Blue) sporting a new pixelated livery, same as per 054 & 055 Blue. T-50-1 made its maiden 47 minute flight on 29.01.2010(last img) & was piloted by Hero of the Russian Federation Sergey Bogdan.

Moderinsed Su-57 developed within the 'Megapolis' R&D framework, to get a new panoramic cockpit display & HUD.
To fly in the summer of 2022 w/ Izd.30 engines (< around 20 built for testing so far). 1/2
iz.ru/1028035/anton-…

Testing of 'Megapolis' to be completed by 2024. Procurement expected in mid-2020's. And the same old line: '76 Su-57s to be delivered to the VKS by 2027' (Highly unlikely! - half of that seems like a more realistic figure)

2nd 'series' Su-57 (51002) from Shoigu's visit to Komsomolsk-on-Amur Aircraft Plant (KNAAZ) today. Was joined by Surovikin,Yevmenov & Krivoruchko.
N.B. I could be wrong, but think that 101KS-V IRST canopy may be different on this a-frame.Also,1st clear img of the radome composite

One more..

N.B. Wonder if this some kind of temp radome?
