Create DNG Profile - Why does it look different in the DNG Editor vs LR/ACR?

Question

Hi everyone, I am sorry if this has been covered before -- perhaps you could give me a link to the relevant info.
I have a client who shoots with a Leica DMR.  The reds are way to saturated and magenta.  We created a new camera profile in the DNG editor using a color-checker chart, shot at D6500 and Tungsten.  Looks great, and Lightroom recognizes it.  The issue:  when we look at a photograph in the DNG editor with this profile, it looks much better.  When we look at the same photograph in LR/ACR with the profile selected, the reds are still too saturated and magenta (though way better than without our profile).  Why would a photo look different in the two applications, with the same profile?

Thank you for any light you can shed on this.

Here is an additional comparison further highlighting the magenta issue (amongst others).  Shot with Leica R9 w/DMR(firmware1.3) using Leica Vario-Elmarit-R 35-70mm at ISO 100, f/4.8, 1/60.  Manual WB=4912K, no Exp Comp.
Here is screen shot of same DNG image. Un-altered in either app., no presets, no sharpening, or noise reduction.  CaptureOne (v4.8.3) on the left, and LR2 (v2.6)
Here is what the above screen shot looks like thru CS3:

Anyone no what's going on?
PS the images were shot just shy of perfect focus to test sharpening in both apps, same levels applied to both images (C1 on left, LR on right).  Here are the results:
