But you cannot 'only' get the first image because the second image (layer) is part of the first image. You can disable this feature with the following define:
I see, that's really unfortunate. Thanks for the info, it's helped me debug further causes for this issue.
It is, however, frustrating that ImageMagick doesn't have a way strip the tags specifying the layer data, as the first image block without the tag data is how Adobe intends for the image to be read outside of the context of Photoshop (at least, according to their spec).

The option means that it will not try to read them and add them to the 'list of images', it will still remain in the file though. You can remove the layers by removing the profile with the name 'tiff:37724'. The following will get you only the first image:
