See my (updated) answer above for an example of the difference.

looking at your dropbox images it is very obvious that the modified images are sharper.

That could be a game changer Will have to try this with a few files, perhaps even some "proper" comparison with and without TC, with and without the hack.

Since this subject needed a refresh for me as well, I took another look at my exiftool scripts today and improved them.
Perhaps also useful for some others?

Using a cmd file that can edit an entire folder.

1) To Update FocalLength (Previous version I set them always to 250 in case >250, now focallength / 1.4
set DngPath="D:\some foldername"
exiftool -overwrite_original "-SerialNumber<focallength" "-focallength<${focallength#;$_*=0.714285714286}" -if "$focallength#>250" %DngPath%

2) RestoreFocalLength; copy previous saved FocalLength back from SerialNumber (contains 'mm') | Can be used for DNG as well as JPG files
Beware, these SerialNumbers are MY serial numbers.
set DngPath="D:\some foldername"
exiftool -overwrite_original "-focallength<SerialNumber" "-SerialNumber=6100229" -if "$Model# eq 'PENTAX K-3' and $SerialNumber=~/mm/" %DngPath%
exiftool -overwrite_original "-focallength<SerialNumber" "-SerialNumber=8085878" -if "$Model# eq 'PENTAX K-3 Mark III' and $SerialNumber=~/mm/" %DngPath%

Bumping because I tried it myself for the first time on a picture taken with DA* 300 and HD DA 1.4x TC, just changed the focal length to 300mm and DxO applied or rather enabled all the lens specific corrections, especially the lens sharpness module has a huge effect imho. Gonna try this on a few others and report back with some comparisons soon.

Here's one I had the urge to try this on, head over to Flickr to pixelpeep the result:

First try with USM for sharpening, DeepPrime noise reduction and a little less extreme editing:

Spread

Now with lens sharpness module, DeepPrime XD noise reduction and a little more extreme editing:

Spread v2

Iím not able to see much difference on my phone. I wonder if a crop of a detailed area would show the differences?

Perhaps you can see it here?

With this shot at ISO 1250 and severely underexposed against the bright sky, so on top of the ISO also heavily lifted exposure, it's also a matter of detail vs. noise. This was at DeepPrime XD noise model +-0. Don't know if the DeepPrime XD issues with the K-3 III are already supposed to be solved or if that is yet to come?
I also played a bit more with exposure, gamma, highlights, contrast,... I think the file could handle it and it looks a little less washed out than before.

That does help. Thanks.
