Baader Herschel prism – Solar continuum with and without IR-cut

For this test, I have taken images with two different cameras. I have used the full-spectrum Olympus E-PL5 with the Baader Solar continuum and ND 3.0 filter for the images without IR-blocking, and the unmodded Olympus E-P5  with these two filters for the system with IR-cut. The question is whether there is any detectable difference between the images taken.

Olympus E-PL5, Baader Solar continuum, ND 3.0 (IR not blocked)
Olympus E-PL5, Baader Solar continuum, ND 3.0 (IR not blocked)
Olympus E-P5, Baader Solar continuum, ND 3.0 (no IR)
Olympus E-P5, Baader Solar continuum, ND 3.0 (no IR)

Click on images for the 100% crops. I do think there is a slight difference with more detail in the sun’s granulation when the IR is not affecting the image. I suspect that the amount of IR getting to the sensor has already been reduced significantly, and perhaps the CMOS sensor of the Olympus E-PL5 is not as sensitive to IR as CCD cameras (where there is a very significant difference with more detail in images not affected by IR).
