Automatically added transformations are a bit dodgy sometimes. I have posted elsewhere that innocent SD DV files are currently interpreted as having been shot with Canon Log C - I have to remove the transformations then transcode the files to something else.

In the Source Settings it looks like this:If I delete all this and hit "Auto" it looks identical on screen to the above but it displays this:
Clearly "Auto" still respects the embedded clip Color Transformation metadata but it doesn't display the list of step yet yields the same results as the laundry list.The kicker is if I take it all of and use the standard Avid Color Transformation it looks different but decent and less crunchy. It may be slightly less saturated and lower contrast but it is a better starting point IMHO:
So why the Laundry list of 5 transforms to get to the same basic place? Am I wrong to be leery of so many manipulations or is that what workflows have become.

I agree I don't trust them but clearly this has embedded meta data with the laundry list of transforms whose ultimate goal is to go from Sony Slog3 to Rec 709 but why pass through S3 to HLG then to 3 flavors of linear to ultimately got linear to Rec 709/2020? It's also Ultra frustrating that when I hit "Auto" button in the Color Transforms window in Avid it puts in the laundry list of transforms but only lists "From Slog3 to Rec709 without showing all the steps in the meta data. Makes it very hard to play along and don't get me started on LUT scaling and whether Avid interprets a LUT as Full Range or Legal Range and is that talking about input level range or output. It would be nice if these under the hood conversions were somehow more visible to the operator.
