Filtering on columns with Conversion

Question

I have a struct that wraps a primitive column value in the database, and I want to apply a filtering query (i.e. a Linq where translated to a SQL where):

Toy example:

struct Dollars 
{
   public Dollars(decimal amount) => Amount = amount;
   public decimal Amount { get; }
   override ToString => $"${amount}";
}

EF mapping:

modelBuilder.Entity<Item>()
  .Property(k => k.Price)
  .HasConversion<decimal>(d => d.Amount, a => new Dollars(a));

Example query:

var expensive = dbContext.Items.Where(x => x.Price.Amount > 1000).ToList();

It seems navigating to properties on my struct (x.Amount) in the filtering is not possible.

System.InvalidOperationException : The LINQ expression 'DbSet().Where(t => t.Price.Amount > 1000)' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation [...]

Is it possible at all to accomplish this somehow, or does primitive Conversion basically only work with identity/equality and not comparison?
