According to some claims up to 70% of corona infections could not result in observable symptoms.
However, if you take just dying people, it would not come as a surprise that they are so weak that the additional infection can produce visible symptoms and their death is attributed to COVID.
In some places in Lombardy (Italy) the death rate is clearly higher. You didn't need the army to transport coffins before. No statistical anlysis required here.
The analysis is further complicated that death rates vary a lot over the year even under normal circumstances. I don't doubt that in some countries a corona peak will be seen, but it will still take months to be sure how big it is.
