Identical peak coverage in IP bam file and Input bam file

Hi,

I had ChIP seq data that I aligned using STAR and got the bam files for and ran peak calling using macs2. I see a list of regions that are enriched, however, when I use the bam file for my IP and bam file for my Input to visualize in the genome browser, those regions do not show any difference in enrichment. Is there a possible reason for this or am I doing something wrong? Any help is appreciated.
