The privacy cases of course involved celebrities so I agree their losses would be worse and perhaps their distress was although I am not sure on distress the court distinguishes in amounts based on how famous you are.
The ICO's website says
"How much compensation will the court award me if my claim is successful?
This will be up to the judge hearing the case, who will take into account all the circumstances. This will include how serious the infringement was and its impact on you, particularly when assessing the distress you suffered.
If the organisation refuses or is unable to pay, you should ask the court how you can enforce the judgment.
You should also bear in mind that the court can award costs to you or against you in certain circumstances. For example, if you fail to demonstrate you have suffered damage or distress, the court will not award you compensation and could order you to pay the other party’s costs. Again, we recommend you seek independent legal advice to allow you to consider the risks of bringing a claim."
I am not in favour of these claims but I just wanted it clear the law allows a claim for emotional distress now even if there is no financial damage (unfortunately ).
Leigh Day solicitors summarise this too:
"Compensation for data breaches
The amount of compensation you’ll receive if you’re the victim of a data breach depends on the exact circumstances relating to the breach, including:
Sensitivity of the data stolen;
How many people accessed your data;
Length of time between the breach occurring and being informed;
How long unauthorised access to the data was / is available ;
Anxiety and emotional distress encountered;
Any financial losses experienced.
You could receive compensation for the loss of control over the information even if you suffered no financial loss"..
