I wouldn't risk the X800 or 850 after having xe9005. OLED isnt that much more expensive then this TV I have just checked. If you buy any display imo you need to buy it at a place where you can return it.
I think you would be better of trying a 43 monitor with IPS, 1000:1, flicker free and W-LED anti glare matte 3h - those are the stuff my monitor 24 has and its night and day vs TV when im on the monitor my eyes fell normal/relaxed I dont think about it.
You cant get 3h surface on any TV, u cant get truly flicker free (even sonys has some flicker/woble at low level backlight leves and I always use low brightness) also I always turn off all the shitty stuff TVs has like contrast enchancer, cine motion bla bla but I feel theres still some image processing being done there... Good monitors are usually very well calibrated while TVs colors calibration are quite shitty Moniotors were always better/no problem for me and problem started on 4k Tvs so I think trying out a monitor 43 is a good idea I know its smaller but if it works it wont be a huge issue.
As for TVs I would only try OLED. If you try anything update
