Somewhat OT -and I may be guessing a bit:
I'm starting to wonder if the reason that there is so much anti-ETTR is because of the pale washed out images on the camera LCD, then pull the image up in LR/CS, and again see a pale washed out image and conclude that the colours are faded.
This is a natural inclination, particularly with printed images - if printed images look like an ETTR image, then they WOULD be washed out and the detail is gone.
BUT - and this is a big but - provided that none of the three channels have been blown out, the ETTR image will have the most detail and therefor the most colour.
It's so easy to be fooled by an LCD (either a camera or monitor).
When the first Nikon D800's came out, many had a greenish tinge on the LCD, but the images were just fine. I seriously think too many judge their images by the LCD - big mistake.
BTW, that shot of the castle really turned out well compared with the undeveloped image.
What you found doesn't really surprise me.

PS - I'm quite open to rebuttals and/or correction.
