### ImageMagick version

7.1.1.6

### Operating system

MacOS

### Operating system, version and so on

Monterey

### Description

The attached image seems to be read as grayscale with alpha in Imagemagick when I believe it should be in color.

identify -verbose says:

```
 Channel depth:
    gray: 8-bit
    alpha: 8-bit

```

But Exiftool says:

```
 0 ImageHeight                     : 10000
    4 ImageWidth                      : 10000
    8 NumberOfComponents              : 4

but it also says

    3 ColorSpace                      : Grayscale

```

NumberOfComponents I interpret as having 4 channels, RGBA, but then it says colorspace is grayscale.  So I am confused about this file.
