Unless explicitly asked for a specific version I’m always on the latest master when doing edits for Pixls. The latest build from this morning tells me I’m on: 3.5.0-2204-g834120353 There have been a handful of merges since yesterday.
My edit uses the latest demosaic, filmic rgb (v5) and color balance rgb the first two have new option and/or are tweaked and the latter isn’t even part of 3.4.X.
I do believe that you would be able to replicate the ART version, but it will take much(?) more work even if you would have access to the latest updates/modules.
I’ve read the other replies and I do have to agree with age when it comes to filmic and how it handles, or mishandles, saturation/chrominance/gamut. This is why I often (have to) change the default preserve chrominance setting in filmic’s options tab and lower the middle tones saturation slider in the look tab.
