There is a comparison. The colors are exceedingly close. The LCD
has, in its normal settings, excessive contrast for film, while
the CT-100 is correct. This can be adjusted out on the LCD set.
The resolution is not exactly the same. The overall resolution is similar,
but the LCD has "sharpening" halos on it, the
CT-100 none, and the LCD has a tad more real
resolution. But very close.

I would love to see screenshots of your comparison test. I think I remember the thread. I could go back and look. I have read in these forums that the CT-100 was possibly the only set that had color phospers that accurately met strict colors standards of that era and up to this day. That means the RCA CT-100 would be considered a high end set of its era and most certainly a better challenge then the field sequential set or the CTC-15. Can the LCD used in your test be considered high end? We're both sets calibrated to the current standard? Today's LCD sets are capable of reproducing a wider spectrum of colors then the current standard. Coming soon, the 4K BluRay group is currently working out the final standards for the new 4K format. LCD manufactures are working to achieve most if not all of the advanced image and color standards of this new format.
My test was comparing Ed Reitan's screenshot to the identical frame captured off my high end Sharp 70 inch calibrated LCD. My LCD model is now three years old. I could post unretouched photos to show what I mean when I say there is no comparison. I can do the same comparison test using a recently adjusted RCA CTC-15 with the LCD. The delta dot structure is much more noticeable on the CTC-15 than the Quatron pixel structure which has 25% more pixels than a standard LCD. It is not as bright. My CTC-15 was adjusted by a retired RCA color technician, but not professionally calibrated. Still the colors do look very accurate.
When the two screenshots of an identical frame are captured from the RCA CTC-15 and the LCD, there is just no comparison in terms of brightness and resolution. The controls for this test are that both sets are in almost total darkness, only the screen light is imaged and captured and the camera is set on auto exposure.
