For the times i worked with OSIRIS i just imported everything in after effects, get a neutral white balance and add the visionLOG profile.
Then i rendered it out (with some minor tweaks if necessary like noise reduction) to prores 4444 which i then import in Davinci.
From that point i start grading, what i find very useful is apply the LUT you want to a Node and then add a node before that one.
Now you have a stylized look that you can tweak but since you are adjusting the node before the LUT you are working with data that could get lost after the LUT (crushed blacks ETC.) so you can use stuff like your highlights and shadows, or just key out the sky and drop it down a notch. whatever you want and in my opinion most of the times this is better than using a Node after the LUT.
Of course most people agree that you should get a neutral picture (color correction) before the node but i find it very useful to see it with the LUT already applied.
BTW, for IMPULZ, i used a combination of 2 LUTs for a videoclip i just did.
The clip however was shot in Cinestyle H.264 but nonetheless, the colors are nice.
I used a Kodak stock from impulz without the film contrast, just the color conversion and then i added the KDX profile from osiris.
The combination of emulating film and then using a stylized look worked just fine to create a very saturated look with the teal orange effect but keeping a bit of a film stock look.
Anyway, downloaded resolve 11, lets see what it can do.
I saw that you can finally get your highlights, shadows, lift and gain in the RAW tab, this could be useful to create a LOG like profile for magic lantern RAW without going to BMDfilm, or use BMDfilm and get the lift up to get a more neutral picture for canon.
