New to 4k. Advice on Dolby Vision and bit depth please!

[Daz_85]

I'm looking to buy my first 4K TV, and currently I'm looking at this model:

This model has Dolby Vision, but the panel bit depth is 8 bit +FRC to approximate 10 bit (as I understand it)... so my question is, is having a TV with Dolby Vision more important than the lack of a "true" 10 bit panel? Or should I be looking for true 10 bit, but settling for HDR10 where DV may not be present?

New to this and trying to catch up, many thanks
