Yes from what I see Don and FASTBOAT TOUGH has right drawing is wrong about PT-91 ERAWA on both sides.
I don't know about massive modernisation of PT-91 to M2 variant looks like that was an demonstrator and probably some of modernisations were implemented in Twardy's tanks in recent years but definitely not a RPG cage in rear
Here you have three PT-91 and T-72

But if you look on that photo this is T-72M1R with Ukrainians additions like RPG cage on rear [taken from T-72AMT modernisation] of tower and Kontak-1 so is possible that they also have since May 2022 some upgraded variant PT-91 Twardy(+)
Here is about this transfer of tanks in January 2023
