imadjust() does not work with RGB images, so it can't take scaling parameters for each color channel. If you want to brighten your RGB image for display, use rescale().

assert(isscalar(app.LowR), "LowR is size %s", mat2str(size (app.LowR)))
and similar for the other bounds

imadjust() does support RGB and full 2x3 limit specification for both lower and upper bounds, and it has for years prior to 2020. The following code was tested in R2009b:
A = imread('peppers.png');
B = imadjust(A,[0.1 0.2 0.3; 0.9 0.9 0.9],[0.1 0.2 0.3; 0.8 0.9 1],1);
imshow(B)
... but it won't work if the input image is single-channel and you give it overspecified limit parameters. Check your input images for class and depth and handle them accordingly.
A = imread('cameraman.tif');
B = imadjust(A,[0.1 0.2 0.3; 0.9 0.9 0.9],[0.1 0.2 0.3; 0.8 0.9 1],1);
It also doesn't support RGB inputs for the short (implicit lower bound) syntax. That requires the explicit use of stretchlim().
