Comping ACEScg renders in Photoshop

Circling back to this.

How would this work if your in ACES but are using the un-tonemapped view?

Un-tonemapped view for ACEScg in PS? just a different lut.

I'm not up to date with news about OCIO in PS but sometime last year PS started supporting bigger .csp luts (1D: 4096 and 3D: 65 size cube). I guess you do not need anything more precise than this.
