why you need to add ****** contrast with an existing "non linear" profile(s) and at the same time don't need to add ****** contrast with linear (which one might assume has less contrast baked in LUTs inside) ? unless you mean not "add" but the opposite

You can use the Adobe DNG Profile Editor (DPE) to change the Base Tone Curve of any camera profile to linear. Instructions here:

https://trentsizemore.com/blog/using-a-linear-camera-calibration-profile/

The DPE edited camera profile needs to be exported to the following folder and LR restarted to load it:

Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \

Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /

Starting with LR 7.3 Adobe added six new 'Adobe Raw' camera profiles including one named 'Adobe Neutral.' The Adobe Neutral profile has a tone curve very close to linear, but without any exposure shift. The DPE created Adobe Standard linear tone curve camera profile shifts exposure in the image by about -.90 EV (see below), which makes it difficult to compare the rendering of different profiles. Give Adobe Neutral a try!

The new Adobe Raw profiles are only available using Process Version 4 with exception of Adobe Standard. From the screenshots I posted the Adobe Neutral profile provides the same contrast rendering as Adobe Standard with a linear tone curve. There's no benefit using Process Version 2 that I can see to reduce contrast even with a linear camera profile. Adobe is not likely to add new camera profiles that are compatible with ANY process version other than Version 4. If the Adobe Neutral profile isn't providing low enough contrast please provide details on your objectives and type of image files you are processing. Perhaps there are other solutions.

you go to Process Version 2 set everthing to zero and set the tone curve to liner then you go back to Process Version4 and you curve should look like in the picture then apply Adobe Neutral then you get the what the raw file Should look like without any added stuff.. :)

I've never seemed to have a problem with it. Just curious if you have any example photos where you're running into this problem?

I often use Camera Faithful with very high-contrast images and for copy work of paintings and film image capture. Adobe Neutral has an even lower contrast curve if needed. Here's an example shot of an oil painting with the same LR settings applied using Adobe Standard (Left) and Adobe Neutral (Right). Which looks better to you?
