Sony 55xf9005 firmware v.6.6545 experience

[vonionel]

Hello

After updating to v.6.6545 from v.6.6510 I experienced next issues :

- overall picture brightness look to be more dimmer and darker

- lost vividness of color 

- much more blooming on subtitle in Netflix app

- a lot of frame drop on 4k hdr 60fps  in Youtube app

Did anyone have this issues?

Hi @vonionel 

KD-55XE9305 zero differences. Perhaps you could try a factory reset.
