As you know the index..you eliminate that particular column from the image.
Try:
I(:,1366) = [] ;
And then use imshow on I.

Use a tophat filter, imtophat(). then threshold that and use it as a mask to replace it with the eroded image (local min). Something like (untested)
badPixels = imtophat(grayImage, ones(1, 3));
mask = badPixels > 4; % or whatever number works.
erodedImage = imerode(grayImage, ones(1,3)); % Get local min value.
grayImage(mask) = erodedImage(mask);
