Patch Generator Choice

Are there advantages one way or another between using PGenerator (on a Pi4 with Ted's Patches) and a monitor output from resolve to generate patches?
I'm thinking that LUT's are a little easier to apply in Resolve than if you're generating them for a LUT box, but I'm not sure which is a better signal chain?

PGen can do 10 bit native, and can have different patch background colours.

Resolve, due to issues with the BMD implementation of patches, can only do 8 bit input, with bit shifting to 10 bit (or other bit depths) on output, and can only use black as a patch background.

The Resolve limitations are stated on the Resolve User Guide.

So Pgen is probably a better choice? Would there be any advantages to using Resolve? I'm thinking if that's what I'm going to be using the display for, does it make sense to use the same signal chain?

Within reason, you should see no difference in the final calibration whichever you use.
Calibrate with one, and verify with the other.

Resolve iTPG is 8-bit while PGenerator is 8/10-bit.

PGenerator can also be used for HDR10 10-bit and Dolby Vision.

If you are going to use Resolve iTPG, you will need 0.75 sec of extra delay, while PGenerator will need 0.5 sec, so the patch generation with PGenerator will be faster.
