What would be the best TV upgrade?

Currently rocking a 55" LG LCD. I'm half looking at upgrading it, but not sure which way to go?

Do I go for a 65" - 75" for the shear immersion, or stay at 55" and go OLED?

Lets say £1k would be the budget? What would you do?

Will be used to view 1080P and UHD content from my home Plex server using a Nvidia Shield as a client. Dolby Vision would be nice - current TV is SDR only. - Main reason I'm thinking of upgrading.

Think I need to get down to a store and demo an OLED again to remind myself of the difference.

BX, CX means nothing to me at the moment. I'll do some research over xmas and see what pops up in a sale
