Í´m going to recalibrate my TV.

Should i calibrate it to SRGB or REC. 709 now if i use the 0-255 Color mode?

Do you have any sRGB sources? Pretty much everything I watch (HDTV, Blu-ray) is ITU.709 based (16-235 4:2:0 YCrCb) with the SD stuff ITU.601 (16-235 4:2:0 YCrCb) based (DVDs, SDTV) with a 601->709 conversion done by whatever is playing/receiving ard/or upscaling. I have a small amount of ITU 709 16-235 YCrCb 4:2:2 content too...

Unless you are shooting your own non-ITU 709 content and watching that - or have a scaler or AVR that is doing a colour space conversion away from ITU. 709 - all of your content is likely to be 601 or 709, and your 601 content is likely to be converted to 709 if you are watching it on a device that upscales.

(601 and 709 have different YCrCb->RGB conversion factors hence the difference and conversion requirement)

Is this technical jargon for "everything is Limited anyway, so why bother unless your Martin Scorsese?" I have a Samsung 4k TV that supports "UHD Color". My terrible interpretation of that mode was "Cool! Isn't that a form of Full RGB?, Should probably turn that on and change my Kodi settings." After reading this, sounds like I should turn it all off and settle back into Limited. I had no other reason to change other than "If my shiny new TV supports it, use it."
