I would like to be able to import a RAW file and have Lightroom NOT put any profile or preset to it.
You can't and in reality you don't want to...an actual linear raw file with zero color or gamma adjustments will look very dark (nearly black) and very green. So, ALL raw processing apps MUST apply a default color and gamma adjustment. ACR/LR does that by applying a DNG Profile (not to be confused with the new appearance profiles).
While you may not think so, Adobe RGB is the most technically accurate color/tone curve rendering of a raw file. Yes, it looks a bit adjusted but if you compare known colors such as on a ColorChecker, Adobe Standard will render those colors and tone patches more accurately than other profiles.
You may not "like" the rendering but that rendering is more accurate.
What you are looking for is a different starting point which by definition is less accurate but a more pleasing (flat) starting point that you then build up to your final result.
Hey, you are welcome to create any starting point you want to...just understand that ANY starting point is an arbitrary non-raw starting point and that all adjustments you choose to make are up to you. If having a more technically accurate starting point hinders your adjustment process, change it...just understand that what you are doing is just as arbitrary (and less technically accurate) than the default Adobe Standard profile will give you.
