What does the TIF look like in LR if you re-import? It seems we're looking at a raw file in LR and a gamut-limited TIF in PS and IV, right?
Do you have a standard-gamut monitor or a wide-gamut monitor?
Is your monitor calibrated with a hardware calibration system like i1DisplayPro or at least ColorMunki or a Spyder? And if so is the profile ICCv2 Matrix or ICCv4 LUT? The ICCv2 Matrix seems to work better.
If not, are you using the manufacturer's monitor profile or sRGB?
Are you using a PC or a Mac and what version of OS?
Do you have some special settings for LR set in your video-card control panel that could be changing the gamma or color balance.
Presumably you've rebooted.
