Apologies for the delay in getting to this one, we will look at it soon

@keshavdalmia10 thank you for taking this on, and I really apologize for the long delay in getting back to you about this PR. I think this is headed in the right direction, but we still need to pass on the EnhancedProcess so that ArgsDisplay is shown to the user.

Actually, I'm not sure that we need EnhancedProcess in pkg/client/inspect_image.go. I would make the changes here:

pack/internal/inspectimage/writer/human_readable.go

Lines 190 to 202 in 4ffdb5e

	var processesTemplate = `
	{{- if .Info.Processes }}
	Processes:
	TYPE SHELL COMMAND ARGS WORK DIR
	{{- range $_, $p := .Info.Processes }}
	{{- if $p.Default }}
	{{ (printf "%s %s" $p.Type "(default)") }} {{ $p.Shell }} {{ $p.Command }} {{ StringsJoin $p.Args " " }} {{ $p.WorkDir }}
	{{- else }}
	{{ $p.Type }} {{ $p.Shell }} {{ $p.Command }} {{ StringsJoin $p.Args " " }} {{ $p.WorkDir }}
	{{- end }}
	{{- end }}
	{{- end }}`

My templating is a little rusty, but you could check out https://gobyexample.com/text-templates as a place to get started inserting the needed logic into the template

As far as I can tell, we set this, but it is never actually used...

This is really testing our call to dist.GetLabel(img, platform.BuildMetadataLabel, &buildMD) - we want to test something that calls EnhancedProcess.ArgsDisplay (but nothing does currently)
