more real graphics on scenes on VR

Hello greetings.
I would just like to know, what is the best way and procedure, to have the best colors and render of graphics, in virtual reality scenes?
any suggestions?
If it is better to leave as UNITY receives the textures, not touch them, and also send them to the lenses?
Or is there any configuration to improve the quality of textures inside virtual reality scenes?

thank you.

 

any idea please ?
thanks

Note the RGSS technique described isn’t something easily implemented into the Standard shader, but the anisotropic filtering & bias doesn’t require any shader changes.
